I have two sets of E-muffs, and a dozen of the green, corded, tri-baffle, silicon plugs. The E-muffs are great. I have a cheap set of Allen's my kids bought me for my birthday one year, and I have a set of Peltor's I got as a retirement gift from the squad. The Peltor's are the high-speed, low-drags with Bluetooth, noise canceling, fancy memory foam padding, Dolby 7.1, built-in PTT mic, fabric top strap so it will fit under a helmet, wired ports for hard connections to radios, virtually all the bells and whistles.
They were my best friend standing on the pump panel. I could walk all around the engine, do work, run the pump, hear everyone around me awesome, not get drowned out by the pump when I was talking, fantastic clarity with the radio.
I hate them, with a passion, when it comes to shooting. Give me my green silicon ear plugs all day long.
